It depends if he's on a broadband, then PopTray can be set to check mail at certian times. As an example, he may be playing his games, while PopTray checking his email, plus Avast also scanning the mail. With having one rule set in PopTray any e-mail detected to have a virus will be deleted.
I have been using this for months and not one virus gets into my Inbox, PopTray can be set to log these viruses that have been deleted. You can also have a rule to delete any suspicious e-mails. Using these utilities keeps my Inbox totally free from viruses, plus 99.86% free of SPAM. I don't have to even look at the mail on the server now before I download it.
